First responders were called to a residence in the 8000 block of Laurel View Drive in the Hollywood area, the sources said. They used naloxone, also known by its trade name Narcan, to reverse the effects of the overdose.

In March, the 25-year-old celebrated maintaining six years of sobriety. Lovato has for years been open about her battles with drug and alcohol addictions, as well as with bipolar disorder, eating disorders and self-harm. She underwent rehab in 2010, at age 18.

Tuesday evening, Lovato's spokesperson told NBC News; "Demi is awake and with her family who want to express thanks to everyone for the love, prayers and support. Some of the information being reported is incorrect and they respectfully ask for privacy."

As news of Lovato's hospitalization spread, friends and fellow celebrities took to social media to express their best wishes.

I love @DDLovato so much. It breaks my heart that she is going through this. She is a light in this world, and I am sending my love to her and her family.

In June, Lovato released a surprise track, "Sober," about relapsing, in which she apologizes for letting down herself, her family and her fans.

In the ballad, she sings, "Mama, I'm so sorry I'm not sober anymore / And Daddy please forgive me for the drinks spilled on the floor / To the ones who never left me / We've been down this road before I'm so sorry, I'm not sober anymore."

"And I'm sorry for the fans I lost who watched me fall again," she also sings in "Sober." "I wanna be a role model / but I'm only human."
